More than one schematic in the same project

Hi,

I am very proud to be able to draw my first schematic ! My friends are surprised !

I belong to a club where whe built and run steam locomotives (around 1/8 scale). We have a layout about 400m long. We have already built signals and points with relays but all the diagrams are handmade on paper.

My first project was building a Kicad scheme of the ‘entry point and signal’ of the ‘station’. I built new symboles, … all is perfect. One thing : we only need .sch file we do not use PCB.

I would like to go on. So my question is : is it possible to have multiple independant sheets in the same .sch file but with sharing the same symbole library ?

Please answer with simple english ! I have difficulties to understand Kicad documentation !

yes, use hierarchical sheets, hotkey is (S)

Strictly speaking the answer ‘yes’ is wrong, because using hierarchical sheets requires several files.

Could the original poster explain more accurately, do you want to use only one file, or is it enough if you can use one project (several files in one folder)?

Having a project specific symbol library is one possible workflow in KiCad. You would have at least

  • The [projectname].kicad_pro file
  • Root sheet file [projectname].kicad_sch
  • The [libraryname].kicad_sym symbol library file, added as a project library in the Project Specific Libraries in Manage Symbol Libraries dialog

Then you can add hierarchical sheets and use the same library in them, but each sheet will be a new .kicad_sch file.

Hi Claudio,

I try to understand Kicad documentation about hierachical sheets. I’ll need some more days to be able to use it.

Hi eelik,

it is enough ! And your answer is “go with hierarchical sheets” right ?

Kicad is nearly french !! I found a french documentation so it will be a lot more simple for me :grinning_face:

Best regards
